Fill in the missing data in the Table
| Species Property | H2O | CO2 | Na atom | MgCl2 |
| No. of moles | 2 | - | - | 0.5 |
| No. of particles | - | 3.011×1023 | - | - |
| Mass | 36g | - | 115 g | - |
Solution
| Species Property | H2O | CO2 | Na atom | MgCl2 |
| No. of moles | 2 | 0.5 | 5 | 0.5 |
| No. of particles | 1.2044 × 1024 | 3.011×1023 | 5×6.022 x1023 = 3.011 x 1024 | 0.5 x6.022 x 1023 x 3 = 9.033 x 1023 |
| Mass | 36g | 22g | 115 g | 47.5g |
